Star Trek: Conquest

In this game players have their choice of six playable races. During their campaign to conquer the Galaxy, players must choose where to mount their offensive and where to hold back and defend. On their turn, players can build or strengthen fleets, advance and attack nearby systems, and engage in real-time space battles or allow simulation to quickly determine the results. The game is won when the player has eliminated all enemy races. (mobygames.com)
